It wiii. be seen that the construction described 'novides o. forward extension of the frames over which cncd boiler E219 can project. The at rem; ncnt therefor provides an increased boiier capacity and the incidental additional Weigl'it is, in the main, carried by the lead ing trncii Without meterialiy adding to the Weight already carried by the drivers. Fur thermore, the construction moves the center of gravity ofthc loed forwnrdiy and thereby niches possibie the appiicetion of e larger fire box, Stoker or booster at the rear of the locomotive Without imposing excessive Weight on the trailer Wheels or rear driver. The added weight insures effective tractive effort which I errenge to make availahlc by means of the booster motor 30 adapted to drive the truck axle 9 through the gearing 31. The forwsrd. tried as usual. upon the axle 9 and toward the rear ofthe booster additional support is provided through the medium of the cross member ,32 between the sides of the frame "5" of the truck 18, the-motor resting upon a rounded seat near the center of the cross member. It Wiil be noted that the cross member 32 "with its seat for supporting the booster is located between the wheels of the truck and its pivot.

Arrangements are made for supplying the booster with steemfrom the main boiler of the locomotive through the pipe 34, the on cerried first i es 3t? formed sag,

' tin baust steam being carried up to the iocomo tive exhaust line through the pipe 35 so 2 to assist in drafting the locomotive.

It will be seen that I have provided a construction which exceedingly simple and yet entirely adequate as to strength; one Which provides a three point support for the load; one which enables me to make use of the weight carried by the leading truck for the purpose of aiding the locomotive in starting or at slow speeds; one which is relatively easy of assembly; and one which, by moving forwardly the center of gravity of the load, makes it possible to apply a larger fire box, stoker or booster to the trailor truck Without imposing excessive weight on trailer Wheels or rear drivers. Many advantages in the construction will occur to those familiar with this art.

I claim i. In a locomotive, the combination of a. unitary front extension member secured to the main frames, a radial leading truck pivoted. to the rear of said extension member a materially frames, the combination of a front extc end of the booster is canneonates receiving iced at said pivot, and means for transmitting iced to the forward end of said truck in front ofits Wheels.

2. In a iocomotive, the combination of e unitary front extension member secured to the main frames, a radial lending truck pivoted to the rear of said extension incinbcr and receiving load at said pivot, means for transmitting load to the forward end of said truck in frontof its Wl'icels, and spring rigging on the truck connected. to the spring rigging of the locomotive.

3. in a locomotive, the combination of e redial leezlingtrnck and centering means be tween the locomotive bumper and said truck.

4. in a locomotive having main side frames, the combination of a front extension for said main comprising :1 inutery side frame structure and bur .per.

6. in a locomotive having main side frames, the combination of a front extension for said main frames comprising a unitary side frame structure and bumper, e, ieading truck, and means for transmitting load to said truck through said. unitary extension.

7. In a locomotive having mein side frames, the combination of 2. front extension for said main frames comprising a unitary side frame and bumper casting, a radial leading truck pivoted to said unitary casting, and centering means between the casting and the truck.

8. In a locomotive having main frames, the combination of 9. front extension for said frames comprising e unitary side frame and bumper, and means for attaching" the locomotive cylinders to said ei'tension,

9. In a locomotive heviiig main side frames, the combination of a front extcnsion for said frames comprising a unitary side frame and bumper, and means for attaching the locomotive cylinders and the saddle to said extension.

10. In a locomotive having main side frames, the combination of a front exten sion for said frames comprising a unitary side frame and bumper, and a loading truck pivoted to said extension.

11. In a locomotive, the combination of a unitary front extension member secured to the main frames, a radial leading truck pivoted to the rear of said extension meml'ocr, and centering means between said member and the forward end of said truck ahead of its Wheels.

a leading truck, and a lengthened boiler ex-v tending out over said casting, the'vvei ht of the boiler being in part at least carried by 'said truck through said casting. v t I 13. In a locomotive having main side frames, the combination of a front extension for said main frames comprising a unitary side frame and bumper casting, a radial its wheels, and booster supporting means on the truck between the pivot and the wheels. 15. In a locomotive, the combination of a unitary front extension member secured to the main frames, a saddle casting secured to said extension member and to the locomotive smoke box, and cylinder castings secured to the extension member between said saddle casting and the main-: f'rames.

16. In a locomotive, the combination of a unitary front extension member secured to the'main frames, a saddle casting secure d to I said extension member and to the locomotive smoke box, cylinder castings secured to the; extension member to the rear of said saddle casting and a locomotive exhaust conduit formed in part in thesaddle casting.

17. In a locomotive having main side frames, the combination of a unitary front extension casting for said main-frames hav ing a plurality of load transmitting means,

a radial leading truck, and a boiler extending out over said castin the weight of the boller .being in part at east carried by said truck thru the load transmitting means of said casting.

18. In a locomotive having main side frames, the combination ofa unitary iron extension casting for said main frames, a radial leading truck, a. lengthenedboiler extending out over said casting, the weight of the boiler being in part at least carried by said truck thru said casting and a locomotive v booster for driving wheels of said truck.

In testimony whereof; I have hereunto signed my name.v
